Worksheet
Two 1 – 6 dice
Mental Learning Objective
• I know my multiplication facts.
Mental Learning Task
• Spend a few minutes asking
the class facts from the
multiplication tables.
• Every now and then stop and
discuss how to work out any
facts they have forgotten.
Mental Learning Objective
• I know my multiplication facts.
Main Learning Objective
• I know the relationship between
multiplication and division.
• I can make rectangular arrays.
• I can write X and 
Key idea
Main Learning Task
• Look at this array.
•Suggest the two multiplications that
describe the array.
Main Learning Task
• Look at this array.
•How could we describe this?
Main Learning Task
• Look at this array.
•What division sentences could I use?
•An example is ‘How many 3s in 24?’
Main Learning Task
• Look at this array.
•How could the 24 counters be
rearranged?
Main Learning Task
• We could write it as 4 rows of 6.
Get into pairs….
Main Learning Task
• We could write it as 4 rows of 6.
Write two multiplication and two
divisions….
Main Learning Task
• We could write it as 4 rows of 6.
How many ways can you rearrange
these 24 counters in rectangular
arrays.
Main Learning Task
• Pairs of numbers 8 and 3, 6 and 4, 12
and 2, and 24 and 1 are all factors of
24.
Main Learning Task
• Simplification : Children can
use counters or squared
paper to model their work.
• Challenge:- Children can look
for the numbers less than
100 with the most factors,
Main Learning Task
• I am now going to give you four
more numbers,
• I want to know how many
different arrays you can make.
• I want four multiplication and
division equations that describe
each array.
Main Learning Task
• Find all the arrays and 4
multiplication and division
equations for
20

42
Main Learning Objective
• I know the relationship between
multiplication and division.
• I can make rectangular arrays.
• I can write X and .
Plenary
• Ask the children to report back
on the work they have done.
• Children working on the
simplification show the arrays
they have made.
Plenary
• Sort out all the numbers from 1 to
36 in the Venn diagram below.
Has a factor of 2
Has a factor of 3
Plenary
• For homework pupils can take home
the Take 5 worksheet and play the
game on their own or with a partner.
Review of Key Idea
• I can review work. I can establish
pairs of factors.

Roll two dice
Arrange to make into 2 digit number
Find every factor of the two digit number.
Cover these with counters.
First to cover a line of 5 squares in the winner.
